What material is the sheath of indoor optical cables made of

Polyvinyl chloride (PVC) is a commonly used outer sheath material for indoor fiber optic cables. PVC is a low-cost material that provides good mechanical protection and resistance to environmental hazards such as moisture and UV radiation. Its primary functions include: While the optical fiber itself remains largely unchanged, the sheath material determines how the cable behaves in fire scenarios, outdoor environments. The jacket material determines the reliability, fire resistance, and lifespan of a fiber optic cable. Three main choices are available: cost-effective PVC, LSZH (compliant with regulations), and TPU (for extreme environments). LSZH (Low Smoke Zero Halogen) 3. TPU. Cable jacket is the outermost layer of the cable, serving as the most important barrier for maintaining internal structural safety in the cable. It can provide mechanical, moisture-proof, fireproof, anti oxidation, and chemical protection for the conductors inside the cable, protecting the cable. The main function of the fiber cable outer sheath is to protect the optical fibers in the optical cable from external damage. At the same time, it must have. Whether you are designing and manufacturing a new cable or simply choosing an existing one for data, power, fiber optics, or industrial automation, the outer sheath (jacket) is much more than just a speaking cover to the eye; it is, in fact, an important job holder in mechanical protection.
